Geochemistry of lithospheric aqueous fluids modified by nanoconfinement.

ABSTRACT: Water is a principal component of Earth's fluids, and its interaction with rocks governs lithospheric geochemical and geodynamic processes. Water-rock interactions are crucial in societally relevant resource management, including subsurface extraction and storage of energy, the deep carbon cycle and generating critical metal deposits. The prevailing view is that fluids navigate through the lithosphere without being influenced by the distinct properties that arise from matter confined at the nanoscale. Here we use electron microscopy and neutron scattering data to show that a diverse range of lithospheric rocks, including sandstones, peridotites and serpentinites, consistently show nanoporosity, predominantly with pore sizes < 100 nanometres. Using molecular dynamics simulations, we demonst
